Apple chose to remove the headphone jack from their flagship iPhones back in 2016, saying that the future was wireless. Apple ditched the headphone jack and started selling their own Bluetooth earphones, “AirPods”. But they didn’t add wireless charging to their iPhones until 2017.

Various other smartphones have had wireless charging for many years; you place the phone on a special inductive pad and you can watch as your phone charges up.

Earlier this week, Huawei announced their new Mate 20 phone which not only can be charged in a similar fashion, but can also wirelessly charge other Qi compatible devices!

On stage, the company showed a photo of their flagship device charging a new iPhone Xs. This reverse version of wireless charging means you’ll be able to charge other devices using the phone’s large 4200mAh battery. For example, if your friends phone runs out of power, you could place it on top of your phone to charge it up.

Maybe the future of powering our devices is wireless; but the technology is still relatively new. Fast food restaurants already have tables with charging pads built in and phones can now charge other phones. But is it really wireless, if you have to place the phone on a pad.. which is plugged in?  

Scientists are building new methods to power devices completely wirelessly using lasers and other electromagnetic technologies. At some point in the future all of our devices will be charged completely wirelessly and even charging a phone via another phone would be considered obsolete.
